[Milapse] picked up a motorized telescope base a few years ago. He’s using it to add motion to time-lapse photography. The base provides two-axis rotation controlled with a handheld keypad. Custom firmware and a bit of software allow for computer control. [Milapse] is pretty well-known in the time-lapse photography circles of the Inter-web. He’s posted a ten minute video explaining his setup and programming work for the hardware.
His use of a quality camera produces some nice video.However cost at $200 for the base, if you just want to play around with the concept you might want to stick to a webcam and LEGO setup.
As much as we love crazy prototype style hacks, we really enjoy seeing things that get used after their creation. [Marcus] sent us the information about his automatic yarn winder. Noticing that his friends who knit had to go through the monotonous process of winding a ball of yarn each time they started the process, he sprung into action. After finding only a few commercial solutions, which were out of his price range, he decided to build his own. He found a hand cranked version and gutted it to add a motor. Now, they simply need to get it started and walk away. Great job [Marcus].
